The climate of India can broadly be classified as a tropical monsoon one. The Indian Meteorological Department (IMD) designates four official seasons:
- Winter, from December to early April
- Summer or pre-monsoon, from April to June (April to July in north-western India)
- Monsoon or rainy, from June to September
- Post-monsoon, from October to December
